Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a manhole cover with an alarm function. Background Art

[0002] In cities, all public water supplies, sewage canals, telephone lines, and fiber optic networks may be connected through underground passages under manholes. Manholes are their exits to the ground and are covered by manhole covers. Underground pipelines are mostly straight. When a turn is required, a manhole is set at the turning position to prevent the straight pipeline from being blocked and to facilitate the installation of pipelines. In addition, for the convenience of work and safety, manholes are set in the middle of a certain length of pipeline to facilitate entry and exit of the pipeline. Manhole covers can cover and protect manholes to ensure the safety of pedestrians and vehicles on the side of the road.

[0003] When the existing manhole covers are in use, if they are forcibly pried open or lost, there is no alarm device, resulting in a lack of warning devices around the manholes, which increases the danger for pedestrians or vehicles passing through. At the same time, when the existing manhole covers are in use, the connection between the manhole cover ring and the ground is mostly connected through a protruding planar structure, so that the connection strength between the manhole cover ring and the road surface cannot be guaranteed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a manhole cover with an alarm function. By setting a buzzer alarm, LED light, positioning sensor and Bluetooth electromagnetic lock, when the manhole cover is forcibly pried open or lost, the Bluetooth electromagnetic lock detects the signal of forced unlocking, and then sends an alarm signal to the buzzer alarm and LED light, so that the buzzer alarm and LED light respectively use sound and light alarms to remind passers-by and vehicles, thereby reducing the danger, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manhole cover with an alarm function, comprising a manhole cover ring, a manhole cover plate is arranged on the inner side of the manhole cover ring, a positioning sensor is arranged on the lower side of the manhole cover plate, a data transmission module is arranged on one side of the positioning sensor, a lock hole is arranged on one side of the manhole cover plate, a mechanical box lock is arranged on the lower side of the manhole cover plate near the lock hole, a Bluetooth electromagnetic lock is arranged on the lower side of the mechanical box lock, an LED light is arranged on one side of the manhole cover ring, and a buzzer alarm is arranged on the lower side of the manhole cover ring corresponding to the position of the LED light. When the manhole cover plate is lost, the positioning sensor can help searchers find the location of the manhole cover plate, thereby facilitating the search. When the manhole cover plate is lost, the LED light can provide a bright light prompt, thereby reminding pedestrians and vehicles to prevent pedestrians or vehicles from falling into the manhole.

[0006] Furthermore, the manhole cover is provided with anti-skid protrusions on the side surface, and the manhole cover ring is provided with a tightening edge on the outer ring side. The setting of the anti-skid protrusions can make the upper side of the manhole cover plate have an effective anti-skid effect to prevent vehicles or pedestrians from sliding when passing through the manhole cover. The tightening edge can ensure that the manhole cover ring is stably connected to the structure paved with the road surface.

[0007] Furthermore, a fixing groove is provided on the lower side of the clamping edge, the manhole cover ring is hinged to the manhole cover plate, and a concrete structure is inserted into the fixing groove, so that the pavement structure and the manhole cover ring are stably connected.

[0008] Furthermore, the LED lamp is connected to the manhole cover ring by bolts, and the mechanical box lock is connected to the manhole cover plate by bolts. The mechanical box lock can stably connect the manhole cover plate and the manhole cover ring to ensure the connection and fixing effect of the manhole cover plate.

[0009] Furthermore, the Bluetooth electromagnetic lock is connected to the mechanical box lock by bolts, and the positioning sensor and the data transmission module are both connected to the manhole cover by bolts. The Bluetooth electromagnetic lock can be automatically opened only when it receives an unlocking Bluetooth signal. If no unlocking signal is received, an alarm signal will be triggered when the Bluetooth electromagnetic lock is forcibly opened, causing the buzzer alarm to sound and the LED light to flash to give an alarm reminder.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the partition wall for steel structure workshop has the following advantages:

[0011] 1. The utility model provides a buzzer alarm, LED light, positioning sensor and Bluetooth electromagnetic lock, so that when the manhole cover is forcibly pried open or lost, the Bluetooth electromagnetic lock detects the signal of forced unlocking, and then sends an alarm signal to the buzzer alarm and LED light, so that the buzzer alarm and LED light respectively use sound and light alarms to remind passers-by and vehicles in time, thereby reducing the danger.

[0012] 2. The utility model provides a manhole cover ring, a clamping edge and a fixing groove, so that when the clamping edge is connected to the concrete or asphalt concrete of the road, concrete can be stuck in the fixing groove, thereby ensuring the connection strength between the manhole cover ring and the road surface structure.
